The global ground-based air defense systems market size was estimated at USD 26.27 billion in 2024 and is projected to reach USD 37.56 billion by 2033, growing at a CAGR of 4.2% from 2025 to 2033. This growth is mainly fueled by escalating geopolitical tensions, increased defense budgets among leading nations, and the rising dangers posed by aerial threats like drones and cruise missiles. These ground-based air defense (GBAD) systems are effective at swiftly detecting, tracking, and intercepting such threats.

The surge in attacks from unmanned aerial vehicles (UAVs), cruise missiles, and hypersonic weapons is a key factor propelling the GBAD market. Modern aerial threats are becoming stealthier, faster, and more sophisticated, pushing countries to invest in advanced, multi-layered air defense solutions. Consequently, defense departments globally are boosting purchases of integrated radar, interceptor missiles, and command-and-control systems capable of simultaneously detecting and neutralizing multiple threats. Technological advances—particularly in artificial intelligence (AI), automation, and network-centric warfare—are enhancing system response times and interception precision, thereby accelerating demand for these defense systems.

The incorporation of AI and machine learning (ML) into ground-based air defense is transforming threat detection and response capabilities, playing a significant role in market growth. These technologies facilitate real-time data analysis, pattern recognition, and automated decision-making, which greatly improve situational awareness while lessening the burden on operators. AI-enabled systems can evaluate incoming aerial threats, rank them according to urgency, and suggest the best interception tactics. This is especially important in complex environments involving multiple threat types such as drones, cruise missiles, and manned aircraft. As defense agencies seek quicker and more autonomous systems, adoption of AI-powered GBAD solutions is steadily expanding.
